Present iviews to be changed to different bcakend system

Question

Hi,
Presently in portal sandbox we have iviews which are connected to BW sandbox (S28).
Our requirement is to use the same iviews and change the connectivity to a newly created BW sandbox (ie S29).Can any one brief me the process to do so.
Thanks,
Sandeep

Not quite sure which direction you are talking about, so I will try to approach both....
(1) The typical System->alias use....
    -create your SYSTEM object (if you have authorization) via "System Administration->System Configuration" navigation path. This is where you would create a general system object...let's say "SAP_BW" and give it the connection info for S28.
     -next, assign that system object an "alias". Call it "BW_SANDBOX".
     -now, you will point all of your iViews to ALIAS "BW_SANDBOX".
     -next, let's say the backend BW changes as you say from S28 to S29. Simply. change the SYSTEM objects info to S29. With that, all the iViews still refer to it because they use the alias and not direct connection information. That's the whole purpose of the design!
(2) Multiple systems from same portal... 
  Now, it might be the case that you are using one portal to connect to two or more same systems (in your case, maybe you want both BW boxes connected).
  -create the system objects for each BW box as described in the other example.
   -assign aliases for both ...let's say "BW_S28" and "BW_S29".
    -Now, you can either change the alias parameter for the iViews you are using to point from S28 to S29 now. OR if you want an iView for each system, I suggest setting the iView's alias to the S28 alias and then copying it to a new iView and changing that one's alias to S29....in effect, having two separate iViews...one for each box...that do the same thing. Make sense?
Hope this helps.
